、用开关电源给步进和直流电机系统供电好不好?
特别是大力矩电机,除非选用比需要的功率大一倍以上的开关电源。因为,电机工作时是大电感型负载,会对电源端形成瞬间的高压。而开关电源的过载性能不好,会保护关断,且其精密的稳压性能又不需要,有时可能造成开关电源和驱动器的损坏。可以用常规的环形或R 型变压器变压的直流电源。
10、想用±10V或4~20mA的直流电压来控制步进电机,可以吗?
可以,但需要另外的转换模块。
11、有一个的伺服电机带编码器反馈,可否用只带测速机口的伺服驱动器控制?
可以,需要配一个编码器转测速机信号模块。
12、伺服电机的码盘部分可以拆开吗?
禁止拆开,因为码盘内的石英片很容易破裂,且进入灰尘后,寿命和精度都将无法保证,需要专业人员检修。
13、步进和伺服电机可以拆开检修或改装吗?
不要,让厂家去做,拆开后没有专业设备很难安装回原样,电机的转定子间的间隙无法保证。磁钢材料的性能被破坏,甚至造成失磁,电机力矩大大下降。
14、伺服控制器能够感知外部负载的变化吗?
如遇到设定阻力时停止、返回或保持推力跟进。
15、可以将国产的驱动器或电机和国外电机或驱动器配用吗?
原则上是可以的,但要弄清楚电机的技术参数后才能配用,否则会大大降低应有的效果,甚至影响长期运行和寿命。向供应商咨询后再决定。
